Melittin dosage and evidence
Written by Aaron CuhaReviewed Sep 2026
The short answer
Melittin is the main peptide in bee venom, about half its dry weight. It punches holes in the walls of almost any kind of cell. Melittin on its own has never been tested as a treatment in people. Whole bee venom has, in studies of 26 to 538 people, with mixed results and a known risk of severe allergic reaction.
Evidence grade for Melittin: Moderate. The rule: at least one finished study in people, and at least 100 people who took it. The sum on this page: 5 completed trials, 658 people given it. A grade counts how much has been done to people, not whether it works.

In plain English
In plain English, from Aaron
This is how I would explain it to a friend. The evidence, with the numbers, is further down the page.
Melittin is the main peptide in bee venom. It punches holes in cell walls and bursts cells. That is part of why bee stings hurt. Melittin on its own has never been tested as a treatment in people. It is not approved for anything.
What people take it for
- Joint pain and arthritis, as bee venom therapy.
- Multiple sclerosis and Parkinson disease, as bee sting therapy.
- Cancer, viruses and skin care, based on lab and animal work.
What studies in people showed
The human studies used whole bee venom, not melittin alone. The biggest had 538 people with knee arthritis. Weekly venom shots for 12 weeks helped pain a little more than histamine shots did. In 54 people with low back pain, venom acupuncture beat a fake version at 3 weeks. In 40 people with Parkinson disease, a monthly venom shot did nothing. In 26 people with multiple sclerosis, live bee stings did nothing. The only study of melittin alone injected 5 mcg into forearms to cause pain for research. It hurt badly.
What people report
Reports, not study results
The good
- People have long used bee venom therapy for arthritis and pain, and the biggest study found a small pain benefit.
The bad
- Pain, swelling, itching and redness where the needle goes in are routine.
- Repeated shots can make you allergic. 4 of 40 Parkinson patients had to stop for that reason.
- Severe allergic reactions and several deaths are on record in people who had used venom therapy before without trouble.
Where these come from: Built from the bee venom papers and reviews on this page, plus the reasons given in the MS and Parkinson studies. No forum posts were used.
My bottom line
My opinion: whole venom may help knee pain a little. Pure melittin is a toxin that bursts blood cells, with a known risk of deadly allergy. I would never inject it.
An opinion, not a finding. I am a coach, not a doctor.

Real people telling you what happened to them. Nobody checked it, and the people who post are not a fair sample, so it cannot prove anything works. It is still the best guide on this page to what people actually do with Melittin, what they expect, and what goes wrong. The full account, including the negative reports, is below.
29 of the 36 indexed goals have no study of any kind behind Melittin
No study in people, animals or cells on this page reports a result for these. That does not prove Melittin does nothing for them. It does mean anything you have heard about Melittin and one of these did not come from a study cited here.

What is Melittin?
Melittin is the main peptide in bee venom, about half its dry weight. It punches holes in the walls of almost any kind of cell. Melittin on its own has never been tested as a treatment in people. Whole bee venom has, in studies of 26 to 538 people, with mixed results and a known risk of severe allergic reaction.
Melittin is a peptide of 26 amino acids. It makes up roughly half the dry weight of honey bee venom. It pushes into cell walls and opens holes, bursting cells without much care for what kind they are. That is why it is studied against cancer cells, viruses and bacteria. It is also why it cannot just be injected. It bursts red blood cells and makes immune cells called mast cells dump histamine. Nearly all serious drug research on melittin is about wrapping it in carriers that keep it away from healthy cells.
What has been measured in people needs careful sorting. Whole bee venom has real human studies, mostly from Korea and mostly as bee venom acupuncture. Venom also contains other active parts, such as phospholipase A2, apamin and histamine. The biggest study had 538 people with knee arthritis. Purified venom was injected at acupuncture points for 12 weeks. Pain scores improved 1.1 points more than with a histamine shot used for comparison. In 54 people with long term low back pain, real venom acupuncture beat a fake version at 3 weeks. In 40 people with Parkinson disease, a monthly venom shot for 11 months did nothing for movement or brain scans. Four were kept out after allergy skin tests flagged them. In 26 people with multiple sclerosis, live bee stings, up to 20 at a time three times a week for 24 weeks, did not cut brain scan damage, relapses, disability or tiredness. A 2018 review warns that bee venom can cause anaphylaxis, a severe allergic reaction. Deaths have been reported in people who had taken the therapy before without trouble. A final-stage trial of a purified venom product for arthritis (Apitox, NCT01112722, 363 people) finished in 2016 with no results posted.
Melittin on its own has been given to people in one published study we could find. In 2000, pain researchers injected 5 mcg into the skin of the forearm. It caused severe short lived pain and a long lasting rise in skin temperature. It was used to cause pain, not to treat anything. No study of melittin alone as a treatment is registered on ClinicalTrials.gov.
In cells and animals, melittin kills tumour cells, knocks out some viruses and lowers swelling markers in arthritis and brain disease models. Wrapped forms of melittin are less toxic than free melittin. Melittin is not approved anywhere for anything.
How does Melittin work?
In people, the only direct measure is the 2000 pain study. Melittin injected into the skin caused instant severe pain. The skin flushed and stayed warmer for over an hour, a sign of nerve and mast cell activity. A numbing gel, lidocaine, cut the flush but not the pain. Everything else about how melittin acts in people is guessed from whole venom, where melittin is one of several active parts. It is also guessed from the well known effects of bee stings. Those are local pain, swelling and histamine release, and in allergic people, anaphylaxis. In a dish, melittin forms ring shaped holes in cell walls, so the cell leaks and bursts. It switches on phospholipase A2, another venom enzyme. At doses too low to burst cells, it changes swelling signals (NF-kappaB and MAPK), lowers swelling chemicals and can make tumour cells kill themselves. In rodents, free melittin bursts red blood cells. It is toxic at doses close to those that affect tumours. That is why the animal work has moved to wrapped or targeted forms. None of these effects has been shown in living human tissue.
What have studies in people found about Melittin?
For melittin on its own: one study, where it was injected into forearms to cause pain. For whole bee venom, which is about half melittin: several studies of 26 to 538 people. Results range from a small pain benefit in knee arthritis to no effect in Parkinson disease and multiple sclerosis. There is also a known risk of severe allergic reaction.
- Whole venom, knee arthritis (2019): 538 patients, 12 weekly sets of skin shots, compared with histamine shots. Pain scores 1.1 points better, function 3.1 points better. Shot site reactions under 5 percent.
- Whole venom, final-stage trial of Apitox in arthritis (NCT01112722): 363 people, finished 2016, no results posted. An Apitox trial in multiple sclerosis (NCT03710655) has an unknown status.
- Whole venom, low back pain (2017): 54 patients. Real venom acupuncture beat a fake version at 3 weeks. Everyone also took a standard anti-inflammatory painkiller.
- Whole venom, Parkinson disease (2016): 40 patients, a monthly shot for 11 months. No effect on movement scores or brain scans. 4 were kept out after allergy tests.
- Live bee stings, multiple sclerosis (2005): 26 patients, 24 weeks. No effect on brain scans, relapses, disability or tiredness.
- Safety (2016 study in 20 healthy adults): venom with phospholipase A2 and histamine filtered out caused less local pain, swelling, itching and redness than unfiltered venom.
- Melittin on its own (2000): 5 mcg injected into the skin of healthy volunteers caused severe short pain and a long skin flush. It was used to cause pain, not to treat anything.
- ClinicalTrials.gov, September 2026: no study of melittin alone as a treatment for anything.
What this does not tell you: None of the bee venom studies separates out what melittin does. Venom also holds phospholipase A2, apamin, histamine and other active parts. The Korean studies also mix venom with acupuncture point needling. The largest good study compared venom with histamine shots. Histamine causes its own skin reaction, which helps hide who got what, but it is not a blank shot. And a 1.1 point pain difference is small. The two brain disease studies found nothing. Nothing here supports using melittin against cancer, viruses or germs in a person. All of that is still cell and animal work. The allergy risk is real. Repeated shots can make people allergic who were not before. The Parkinson study had to drop 10 percent of its people for that reason.
What do people who took Melittin report?
This is what real people say happened to them, good and bad. Nobody measured it. A report cannot tell a real effect from the lift people get just from expecting it to work, from a diet or training change made at the same time, or from what was really in the vial. We still put it near the top. It is the next best thing to a study in people: what happens when real people use it, including what goes wrong.
- Bee venom therapy, with live stings or injected venom, has a long tradition among ordinary people for arthritis, multiple sclerosis and long term pain. The 2005 MS study was run because patients were already doing it. The Parkinson study used a standard allergy shot dosing plan for the same reason.
- Korean papers on venom injection and the 2018 Toxicon review describe pain, swelling, itching and redness where the needle went in as routine. It lasts hours to days, and it is worse with unfiltered venom.
- Becoming allergic after repeated shots is documented in studies. 4 of 40 Parkinson patients tested positive on allergy skin tests during monthly shots and had to stop. The Toxicon review records anaphylaxis and several deaths in people who had taken the therapy before without trouble.
- Bee venom skin products are sold for the face and skin. We found no study in people comparing a melittin skin product with a dummy.
- We found no record in any source of how people use melittin sold as a research peptide for injection. What is known about injecting it comes from one pain study, where 5 mcg caused severe pain.

The state of the research
Melittin sits where two fields meet that rarely talk. Drug researchers see it as a lead compound whose hole punching power is the problem to engineer around. That is why recent papers are about tiny carriers, microneedles and add-ons, and why none of them involve people. Bee venom therapy treats venom as a traditional remedy, and it has run the human studies. Almost all used whole venom. Many were in Korea, where bee venom injection is an established practice. A few were in Europe, where patients were already using bee stings for MS and Parkinson disease. University groups there tested whether it did anything. Those European studies were run by hospitals and universities, not by anyone selling venom, and they found nothing.
The one large good study, 538 people with knee arthritis, does not say who paid in its summary. It calls itself a final-stage trial of a purified venom product. Separately, Apimeds registered a final-stage trial of its purified venom product Apitox in arthritis. It finished in 2016 with 363 people and never posted results. The records do not show whether the two are linked. A published good study next to an unreported one for the same disease is worth noting either way. What nobody has paid for is a study of melittin itself. The reason is the drug, not the money. Free melittin bursts red blood cells and triggers mast cells at doses close to any useful dose. There is no obvious safe way to give it into the body. Products sold as melittin or bee venom peptide for injection are selling a toxin that bursts blood cells, with a known risk of severe allergic reaction and no human treatment study.

The studies we cite
- Study in people2000Computer-assisted infrared thermographic study of axon reflex induced by intradermal melittin
The only human study of melittin on its own used it to cause pain, not to treat anything. A tiny amount was injected into the skin of the forearm. It hurt badly, and the skin flushed and warmed for over an hour. The researchers were studying how nerves respond, and melittin was simply the thing that hurt. Nobody was treated for any condition. This is the entire human record for the isolated peptide.
The only located human study of isolated melittin. 5 mcg injected intradermally into the forearm caused severe transient pain and a rise in skin temperature peaking at 10 minutes and lasting over an hour. Melittin was used as an experimental pain stimulus, not a treatment. Academic study, Japan.
- Study in people2019Efficacy and Safety of Honey Bee Venom (Apis mellifera) Dermal Injections to Treat Osteoarthritis Knee Pain and Physical Disability: A Randomized Controlled Trial
This tested whole bee venom, not melittin. Five hundred and thirty eight people with knee arthritis got weekly skin injections of venom, or of a control substance, for twelve weeks. Pain and physical function improved more on the venom. The gains were modest in size. Reactions where the needle went in were uncommon. Melittin is one ingredient of bee venom, and nothing here tells you what melittin alone would do. The paper does not say who paid.
Whole purified venom, not melittin. 538 patients with knee osteoarthritis randomised 1:2 to histamine control or 100 mcg venom in 15 dermal injections at acupuncture points weekly for 12 weeks. WOMAC pain improved 1.1 points more than control (95% CI 0.3 to 2.0, p = 0.001) and physical function 3.1 points (p = 0.0046). Injection site reactions under 5 percent. Described as a phase 3; funding not stated in the abstract.
- Study in people2016Bee Venom for the Treatment of Parkinson Disease: A Randomized Controlled Clinical Trial
Bee venom did nothing for Parkinson disease. Forty patients got a monthly shot of venom or of salt water for nearly a year. Movement symptoms were no better on the venom, and brain scans showed no difference either. Four people were kept out after allergy testing flagged them, and nobody had a whole body allergic reaction. Forty people is small, so this rules out a large benefit rather than a small one. Paris hospitals ran it.
Whole venom. 40 patients with Parkinson disease randomised to monthly subcutaneous bee venom 100 mcg or saline for 11 months. No significant change in UPDRS III motor scores or dopamine transporter imaging. 4 patients excluded for positive allergy skin tests; no systemic allergic reaction. Academic trial, Paris hospitals (NCT01341431).
- Study in people2005A randomized crossover study of bee sting therapy for multiple sclerosis
Bee sting therapy failed on every measure it was tested on. Twenty six people with relapsing multiple sclerosis were stung up to twenty times a session, three times a week, for six months. Brain scans showed no fewer new lesions. Relapses, disability, fatigue and quality of life were all unchanged. Nobody was seriously harmed. The comparison was against no treatment at all, so everyone knew what they were getting. A Dutch team ran it.
Live bee stings, up to 20 per session three times weekly for 24 weeks, versus no treatment, in 26 people with relapsing MS. No reduction in new gadolinium enhancing MRI lesions, T2 lesion load, relapse rate, disability, fatigue or quality of life. No serious adverse events. Academic trial, Netherlands.
- Study in people2017Efficacy of Bee Venom Acupuncture for Chronic Low Back Pain: A Randomized, Double-Blinded, Sham-Controlled Trial
A small study found less back pain after bee venom acupuncture. Fifty four people with long standing low back pain had six sessions over three weeks, either the real thing or a fake version, on top of a painkiller everyone took. Pain, bother and function all improved more in the venom group at three weeks. Fifty four people over three weeks tells you nothing about lasting benefit. Side effects were minor. Korean academic funding paid for it.
54 patients with non-specific chronic low back pain, six sessions of real or sham bee venom acupuncture over 3 weeks on top of loxoprofen. Bothersomeness, pain intensity and function improved more in the venom group at 3 weeks; minimal adverse events in both groups. Korean academic funding.

Common questions
What is the Melittin dosage?
No human dose established. Amounts that were given in studies sit in Human evidence on this page. None of them is a personal dose. 5 completed trials, 658 people given it
Is Melittin FDA-approved?
Not FDA approved. No study giving pure melittin as a treatment is registered. Whole bee venom extracts are approved only as allergy shots for bee sting allergy, which is a different use.
Has melittin been tested in people?
As a treatment, no. The only published human study injected 5 mcg into the forearm to cause pain for research. Whole bee venom, which is about half melittin by weight, has been tested in studies of 26 to 538 people. It gave a small pain benefit in knee arthritis and low back pain. It did nothing in Parkinson disease or multiple sclerosis.
Does bee venom help arthritis?
In the largest study, 538 people with knee arthritis got weekly venom shots into the skin for 12 weeks. Their pain scores improved 1.1 points more than a group given histamine shots. That is a modest effect, unlikely to be chance, in one study that does not say who paid. A separate final-stage trial of a purified venom product finished in 2016 and has never reported.
Is melittin an anticancer or antiviral drug?
In cells and animals it kills tumour cells and knocks out several viruses, and reviews of that work exist. No person has had melittin for cancer or a virus in a study. The reason is that free melittin bursts red blood cells and triggers mast cells at doses close to the ones that would be needed.
What is the risk of injecting bee venom or melittin?
Pain and swelling where the needle goes in are routine. Repeated shots can make people allergic who were not before, as happened to 4 of 40 patients in the Parkinson study. Severe allergic reactions, including deaths in people who had taken venom therapy before without trouble, are recorded in the reviews. Melittin alone at 5 mcg caused severe pain in the one human study.
